| Abstract: | Some arguments for the explanation of the spectroscopic and photometric behavior of CH Cyg in terms of an eclipsing binary with P=5700 days, consisting of M6 III star and an accreting white dwarf, are presented. Physical and geometrical parameters of the system have been estimated and discussed.Paper presented at the IAU Colloquium No. 93 on  Cataclysmic Variables. Recent Multi-Frequency Observations and Theoretical Developments , held at Dr. Remeis-Sternwarte Bamberg, F.R.G., 16–19 June, 1986. |
